Title: debris filter for syringe
Inventor: MOON SEONG PIL
IPC: A61M5/31
Filed: 2019-05-08
Abstract: The present invention relates to a foreign matter safety filtration device for a syringe which performs first filtration of foreign matters such as glass fragments from injection vial made of glass material by a first filtration filter unit when an injection drug is sucked into a syringe barrel side by the first filtration filter unit and a second filtration filter unit provided inside a syringe barrel, and performs a secondary filtration of foreign matters such as glass fragments by the second filtration filter unit when the injection drug is discharged, to prevent the foreign matters such as glass fragments from being injected into the human body in advance when the injection drug is injected. In addition, the foreign matter safety filtration device for a syringe is capable of preventing needle puncture accidents caused by slipping during injection drug filling, as nurses with relatively little grasping power can easily and simply fill the injection drug into the syringe barrel, because the first filtration filter unit and the second filtration filter unit are opened and blocked when the injection drug is sucked and discharged, and pulling a syringe piston and filling the injection drug into the syringe barrel can be done easily. Since a space can be secured in a filter hub provided with the first filtration filter unit and the second filtration filter unit, the resistance to the applied vacuum pressure does not work so much that the injection drug can be easily injected to the patient′s body.
